specification of Letters Patent. Patented Allg. 15, 1911.

To all whom 'it may concern:

Be it known that I, IGNAZ BEissEL, mining assessor', a subject of the King of Prussia, residing at No. 1S Klcinklnstrasse, Aix-la-(lhapelle, in the Kingdom of Prussia, Empire of Germany, have invented certain new and useful Improvements in Cutting-Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for cutting coal and other mineral, in which the rotary cuttingwheels are directly driven by a motor-device similar to a turbine.

What I have invented to improve such vices within the rotary cutting-disks, these being hollow, whereby the pressingmedium is guided through the nave of the stationary parts of the driving-devices to the cutting the driving-devices. By this arrangement the following advantages over what is known heretofore `are gained. (l.) In a cutting-wheel of certainV height there are obtained for the pressing-medium the greatest pressure-surfaces imaginable which, in their turn, cause an increased capacity of the cutting-machine. (2.) By the formation of the two cutting wheels as hollow disks, guided by the stationary parts forming a double-wheel, each singlecutting disk receives the form ofan independent radialturbine so that in the case of opposite rotations the transverse strains compensate each other. The form of the cutting disks as hollow-disks allows of giving to the journals a diameter as small as possible so that the weight of the machine is reduced and the construction is simpler at (et.) By the directrix-wheel being a double wheel, the giving-ott|` of power to the cutting disks can take placey as close as possible to the cutting-face by means of a pressure-tmbine therebybeing attained an economical driving. Owing to the fact'that the pressing mediumA enters into the cutting-disks through the nave of the stationary directrix wheel, the proportidn between the circumference` of the rotor,'tl iat is to say the working-face of the machine, on one slde and t-he inslde width of the feedingipe on the other .canv be made most favorab e. (6.) The compulsory guidance of the pressing medium through the directrix-wheel forming a double wheel and through the rotors allows the pressing medium, especially if ywater under pressure is used, to leave the rot-ors that is to say the cuttingpdisks immediately before the cutting-teeth and thatin the direction opposite to the rotation. In this way a proper cooling of the cutting-teeth, a direct watering of these cutting-teeth and of the heling is attained. Further the formation of coal-dust and sparks is prevented thereby.

As my improved cutting-machine can be manufactured.in any size, especially as a hand-machine of light weight', so that it can vbe easily handled by a workman, the purposes ot mining are mostly taken into ac- Fig. 2 is a horizontal section through the' center of the cutting-wheel. Fig. 3 is a vertical section of F ig. 2. Fig. 4 is an enlarged fragmentary elevation, showing a portion of the cuttingmembers broken away and in section to bring out details of construction, a modification of my invention.

The illustrated machine lforms a radial double turbine. At both sides ofthe feedtube 1 for the pressure-medium the rotors2 arearranged. The feed-tube, close to the machine, is flat. The directrix-wheel 3 is arranged inside of the rotors, said directrix-wheel being stationary and having the forml of a double wheel. Its hollow nave l is held by the feed-tube 1 and communicates through canals 5 with it. Thel directrix-wheel is preferably composed of two separa-te wheels engaging each vother by means of nave-parts forming gearings. To

prevent the directriX-wheel. 3 fromV turning' out of place toward the feed-tube llthe at-` tachments 6 on the latter are provided to enter the nave of the directrix-wheel. The

channels '7 in thedirectriX-wheel lead from .A the hollow nave to the peripheries and form' near to the peripheries the directrixblades. The position ofv theblades Sfof the rotors is clearly 'shown inv Fig. 2. In-

stead of arranging only the few villustrated channels 7 Whole the peripehries o :f the directrx-wheels can be provided with direcfio in particular tobe such that they form a pressure-turbine and that 1f water 1s used,

let the latter pass out p backward. This' form of construction of the blades makes it possible to use the water on one hand for cooling and washing the cutting teeth and on the other for rapidly removing the cut material. Y The connection of the two halves of the directrix-wheel 3 as well as those ofthe rotors 2 surrounding the same is effected by the bolt 10. The latter is introduced, after the single halves consisting each of a directriX-wheel and a rotor, have been placed upon the feed-tube 1, and it thus forms, at the same time, the connection between the feed-tube 1 and the halves of the directrixwheel 3. All parts to be connected by means of bolt 10 may be' such that the two halves of the coal-cutting-machine rotate in the same direction 0r also 1n opposite directions. In Fig. 2, the device is shown to opcrate with the cutting members rota'ting'in the same direction, While, in -Fig. 4t, the cutting members are adapted to rotate in' opposite directions. This difference in rotation is accomplished by the direction of inclination, with respect to 'the plane ofthe members, of the cooperating channels 7 and 8, yas clearly shown in the drawings. ln each onefof these cases they can either rotate independently of cach other, or they may be in connection with one another' and rotate in the same direction.

In the form of construction indicated the rotors y 2 are independent. The bolt 1t) presses twodisks 10, between which three.

lies a packing 10, against the piece 11 ot' tube 1. The space remaining between the bolt 10K and the piece 11 of tubel serves as an oil-reservoir 11 for the roller bearings .12 by means of which and of roller-bearings ,i113 lthe rotors 4run over the stationary parts.

v'ijiforder to bel able to wash the slot be- .tween vithe cutting-wheels, the flat end-piece "of'fecd-tube 1 is provided with jet-openings 14.

`ln detail the course ofl the pressure medium of the machine is as follows: The pressuremcdium enters into the tube l and by means of a bifurcation it passes through the openings 5 into the dlrectrix-wbccl 3. From this it streams tlirough the dlrectrix-blades are "thereby put;

'des '8p of the rotors, which ,.7 againstthef If, in par- 'into' rotation.

ticular water is used as pressure-medium, it passes through the rotary-blades 8 and at the periphery of the rotors it passes out cleaning and cooling the cutting teeth by a stream inopposite direction, after having put-the rotors in rotation and given olf its power.

For the protection of the attendant there may be arranged in front of the back of the cutting wheels 2 a protecting-screen 15, which is to be of the height of the cutting wheels and forms a protecting closure when the coal cutting machine has entered the hole. ,Tn the form of construction indicated the protecting screen further forms an oilreservoir for the ball-bearings. The lubrication takes place through the canals 16 soy which are arranged in the frame and have,A

their continuation in canals of the nave of` the directriX-wheel F or handling this screen 1s arranged at the end of a frame the length of which can be varied and which is to be fiat in a mannerthat it can -be introduced into the hole and serve lto the cutting wheel as a guide. lThe cuttingmachine is taken at the cutting piace and pressed against the same, while the pressure-medium streams through the feed-tube and puts the..I

cutting-wheels into rapid rotation. The cut material loosened by the cutting teeth is washed away bythe pressure-medium, and

if water or steam is used asa pressure medium, thcsame is partly or`full`y absorbed by the cut material.. In this way there are produced two strips lof the thickness of the ,two cutting wheels.

The coal strip theoretically remaining between the two strips of a thickness of about '10 mm. of the slot of,n

with in most cases, so that on the whole there-1:.;

is formed a cut 'of the height of the cuttingwheel. s i

lf the cutting-machinehas cut itself into the hole, the following frame which can be lengthened requiredservesit as a guide,

If the two cutting-wheels run in. opposite directions the power required for holding the cutting-machine smaller than with cutting-wheels running in the same direction, as in this case the pushing forces oe-.

cui-ring in consequence of the resistance of the cutting surfaces compensate each other for the greater part.

When using pressure-air or electricityfor driving the cutting-wheels there may be arranged a special washing device for convey- 'ingolf thedcut material and for avoiding the `formation' of coal-dust and sparks.
